[18F] Experiencing hand tremors, nausea, and blurry vision

What might be happening

Based on the symptoms you've described, there are a few possible explanations:

• Anxiety or Panic Attack: You mentioned that your symptoms seem to worsen when you're overthinking and improve when you're distracted. This, combined with your symptoms of shaking, nausea, blurry vision, heavy breathing, chest tightness, and heart racing, could suggest an anxiety or panic attack. These symptoms can be very scary, but they're not usually harmful. Your family history of anxiety could also be relevant here.

  • Treatment typically involves cognitive-behavioral therapy and, in some cases, medication.

• Hyperthyroidism: This is a condition where your thyroid gland produces too much thyroid hormone. This can cause symptoms like shaking, heart racing, and feeling hot. Your age and sex make this a possibility, although it's less likely given your other symptoms.

  • Treatment typically involves medication to reduce thyroid hormone production.

• Side effects from energy drink: Energy drinks can sometimes cause symptoms like shaking, heart racing, nausea, and anxiety, especially in people who are not used to consuming them. This could be a possibility given your recent consumption of an energy drink.

  • Treatment involves avoiding energy drinks and other high-caffeine products.

What you can do

1. Try to stay calm. I know this is easier said than done, but try to focus on your breathing. Take slow, deep breaths in through your nose, hold for a few seconds, and then exhale slowly through your mouth. This can help to slow your heart rate and reduce feelings of anxiety.
2. Avoid caffeine and other stimulants. These can worsen your symptoms.
3. Seek help from a healthcare professional. They can provide a formal diagnosis and appropriate treatment.

What you should look out for

Please seek immediate medical attention if you experience any of the following:

• Severe chest pain
• Difficulty breathing
• Fainting or loss of consciousness
• Severe abdominal pain
